I am trying to implement a unit quantity notifier in the header, that displays the number of items currently in the cart. I have set up two successful services, one that sends data to the header when there is a HeaderPageletLoadedEvent, and the other to pull data from the cart when there is a CartChangedEvent.
The issue is that I cannot seem to save the event / page details of the Header during the CartChangedEvent, and vice versa, as these seem to access the service page independently of each other. As a result, I am not sure how I am supposed to send the cart content information to the header.
Any ideas on how to do this?
